Plug socket for miniature relays

The present hiring relates to a plug-in socket made of insulating plastic for miniature relays and it relates in particular to plug-in sockets, which are arranged in a none close to each other,

Consultation time by arrangement

soclsss on a relatively small Hardly a :; if possible there is space for a large number of such electrical relays.

With such jacks arranged close together for small relays it is vd.ch.tig to take precautions, that when plugging in a relay in the corresponding socket There is a guide so that the numerous pin contacts can be plugged into the socket contacts cover, which makes it easier to plug in the relay and prevents the pin contacts from bending is & it is important that the shielding metallic lielais cup when inserting the heater into the socket before the pin contacts penetrate into the corresponding one Base contacts are effectively and safely earthed, so that in the event of a ground fault within the Eelgis, the operating personnel is protected from this by means of live parts To come into contact "outside" is the safe and secure option Effective earthing of the metallic Seiais cup is essential for effective shielding of the components of the Seiais is guaranteed.

¹ S plug-in slots for miniature relays are known which are used for

Purpose of the recovered guidance of a heater, for example designed as a flat prism, are equipped with k guide walls which guide the relay in such a way that all pin contacts of the same when inserted into the sockets are brought into exact congruence with the corresponding socket contacts. For the purpose of grounding the shielding Belaisbecher, the well-known Heiais Hit are equipped with an additional grounding pin connected to the Sslaisbecher, which is advantageously designed with a greater length than the other pin contacts so that the Belaisbecher even before the other pin contacts are inserted into the corresponding Base contacts are effectively grounded.

It is a major disadvantage of all plug-in sockets equipped with 4 guide edges for the Heiais that the wall thickness of the guide walls not only increases the installation length but also the width of the plug-in socket considerably. In closely arranged jacks, these all-round enlarge the Sinbauraaße is very unfavorable _t since only a smaller number of jacks may be arranged in a limited space.

The arrangement of an earthing »pin contact with a greater length in the known embodiments of plug-in socket for small «

relay has the major disadvantage that the leading Connection of this pin contact with the shielding hot cup is very difficult, since most of them are made of aluminum A conventional soldered connection cannot be made in the cups and, in addition, a conductive connection can be made Connection after assembly of the relay body within the Relay cup is no longer possible. Another disadvantage of the Seiais with a ground pin contact is that in the Socket base plate an additional socket contact is provided must be where $ by the mutual spacing of the socket contacts and. so that the electrical creepage distances are reduced »

Bs is an object of the present furnace, an improved jack for miniature relay, grazing in which avoids the disadvantages of the known jacks and which ensures despite reduced Slinbaumaße a secure guidance of the male Heiais and safe grounding of the shielding relay cup without sin additional Srdungs- Pin contact and thus an additional base contact must be provided in the socket.

The solution to this problem is new, as in the case of plug-in sockets from ir s ο Ii er en your plastic for electrical relays with

arranged vertically to the mounting plate in the socket base plate Socket contacts for inserting the pin contacts of the Seiais by placing the socket base plate with two guide pieces made of the same plastic for the shielding Seiais cup and with it ::! fitted earthing leaf springs ivird.

According to this innovation, the socket base plate instead of the usual equipment with 4 guide walls only equipped with 2 guide pieces, xvelche for prism-shaped, Flat Eelais can be arranged either on the long sides or on the broad sides. The juxtaposition of eggs individual plug-in settings then always take place those sides of the jack are against each other, which are not are equipped with guide pieces, so that a larger number of such plug-in sockets even with limited installation space can be strung together. The shielding Seiais cup is not grounded via a pin contact of the Eelais which in a socket contact of the socket penetrates, but by grounding leaf springs, which are when Inserting the seiai into the jack to the metal that Put on the relay cup and effect a safe grounding of the same and. before the individual pin contacts of the Seiais into the

penetrate the corresponding socket contacts of the socket and be rested on tension *

For an economical production of the innovations trained It is advantageous if the plug-in sockets are carried out in one operation with the rectangular socket base plate pressed guide pieces on the narrow sides of the base plate and placed at right angles by this.

If, according to the innovation, the guide pieces lie on the narrow sides of the socket base plate in the case of prisiaenf örjiiigen Beiais ± Hfes3nHg due to the low installation price of the plug-in socket a large number of such versions can be strung together. The lateral guidance on the long sides of the prism is deliberately omitted and is also not necessary because the other Seiais lying close to the empty socket provide a secure guide for the broad sides of the one to be inserted Form heiais.

For an effective and safe contact between the earthing leaf springs and the shielding hot cup, it is important

that the grounding leaf springs are elongated and vertical E-grooves lying on the socket base plate on the facing Inner surfaces of the guide pieces are arranged.

Due to the elongated design of the earthing leaf springs, these are located on a relatively large length to the Helais beaker and cause a safe ground contact. The grooves in the inner surfaces provide every Saiim for the resilient movement of the earthing leaf springs, so that the sliding «-» process is not hindered.

To the grounding leaf springs the required preload in sighting to lend to the Seiais cup, it is important that the Srdungs « leaf springs arched from the inner surfaces of the guide pieces and consequently, the Hid is resiliently fitted to the hot cup to be inserted are trained

- A great advantage of the plug-in socket designed according to the innovation compared to all known plug-in sockets is characterized by the fact that the upper, the, base contacts are sent Ends of the grounding leaf springs are interlocking, but can be pulled out and protected against accidental contact. The plastic material of the guide parts is arranged.

w 8 <- ·

The form-fitting arrangement of the upper ends of the Sr leaf springs4 ensures a secure hold of the same, but allows one in the training according to the innovation easy replacement of the ID sheet spring, if the spring tension should subside for whatever reason, or if Uelais is prone to short-circuiting when an ax is pushed in Burning phenomena occur on the spring, with the known Jacks is an exchange of the plug contacts, in case - they show signs of burning, only badly or even at all never possible

In connection with the easy interchangeability of the leaf springs it is important} that the lower ends of the grounding folate springs facing the socket contacts are extended and loaraüsl to the socket contacts through slots in the Socket base plate passed through it so that it can be pulled out and the underside of the socket base plate is formed so that it protrudes significantly are.

A particularly correct IT control mark can be seen in that protruding from the underside of the base plate Ends of the grounding leaf springs at right angles to the outside protruding, bent and designed as solder connections.

Due to the rectangular ikbbie'sung the lower extended ends of the ürdungsblattfedern v / ill be unintentional displacement thereof ± n the guide grooves prevented without be expressed from the leaf spring holding tongues need.

The new training of the lower earthing leaf springs also has the great advantage that when assembling the Plug-in socket on a mounting plate made of electrically conductive Material on a soldering of the earthing leaf spring with the cash line can be dispensed with by sticking out to the outside «- the ends as a Kleumlasche for attachment through the Holding screws of the plug-in socket between the socket base plate and the mounting plate are formed.

Since the lower extended ends of the 3räungsblattfedern are located between the base plate and the mounting plate and the retaining screws of the plug-in socket are clamped between these components when the lower extended ends of the 3räungsblattfedern are used, a secure contact is made with the metal mounting plate without an additional soldered connection and thus a secure grounding causes · TJm the Eontakt zv. improve, it is advantageous to pull a tongue out of the clip to the left

In one operation with the rectangular socket base plate 3 pressed, guide pieces 8, 9 are arranged on the narrow sides of the same, which protrude at right angles from the socket base plate and serve as a guide with the facing inner surfaces 10, 11 when the relay 2 is inserted. In these facing inner surfaces 10, 11 hats 12, 13 lying vertically to the socket base plate 3 are arranged, which in axial sighting coincide with slots Ik, 15, which are obstructed parallel to the .Sockelkontakten 6 by the Fas sun gs base plate 3. In the hats 12, 13 elongated earthing leaf springs 16, 17 are arranged, which are abi7Ölbt from the inner surfaces 10, 11 so that they spring against the narrow sides of the relay 2 as soon as it is pushed into the socket 1. The upper ends of the grounding leaf springs 16, 17 facing away from the base contacts β can, however, be pulled out in a form-fitting manner.

A particular advantage of the design of the leaf springs 16, 17 according to the innovation is that when the plug-in socket is installed on a metal mounting plate k, no soldered connection is made, since the extended ends protruding outward, for example as shown in the figures, the extended end 25 between the socket base plate 3 and the mounting plate is eingeklsmsrb and but a secure ground contact is not obtained, ^ s is advantageous in such a case, necessary to form this extended end 23 as IilemHlasche and xrelche equipped with an expressed tongue 26 is biased by a slight curvature and the ground contact improved

One can see from the figures that the guide pieces are 8,9 disposed only on the narrow sides DER jack 1 so that the Sinbaubreite this jack is _t extremely small, and make a close juxtaposition of a plurality of such jacks on verhältnisBiässig small Saura "A guide of Ealais 2 on the long sides of the heaters is also not necessary "because the relays next to them may be arranged close together" form an effective guide when inserting an exchanged ilelais.

Although the present description is essentially

refers to plug-in sockets for relays in flat prismatic form, must be stipulated that the renewal Training and arrangement of earthing leaf springs can also be used with plug-in sockets if this is the Used to accommodate differently trained relays in relation to the drawings and, for example, cylindrical or ■ have triangular fora, without thereby the uahraen of registration and claims is exceeded.

It is also essential that the connections of the grounding springs have a spacing of own the contact pins of the socket.

In particular from FIG. 2 it can be seen that the slots IS, 17 of the socket contacts 6 one of the grid dimensions corresponding Have a distance, this results in a simpler day / and use in standardized circuits.
